To all 'whom t may concern.'

Be it known that we, EARL G. LINKHART and RALPH H. LINKHART, citizens of the United States, residing at North Vernon, in the county of Jennings and State of Indiana, have invented new and useful Improven ments in Separators and Graders, of which the following is a specication.

This invention relates to separators and graders, and it has particular reference to an improved machine for separating and grading cracked corn.

An object of the invention is to produce a. simple and efficient machine, whereby cracked corn may be separated into various grades of fineness,-such as coarse corn for chicken feed, ne cracked corn for chick feed, bread meal and bran. The present invention is an improvement over the structure shown inthe patent to John W'. Linkhart, No. 1,112,302, issued September 29, 1914.

When corn is ground for chicken feed, it is reduced to a mixture of particles, some of which are comparatively large, some small, some in the formy of meal, and the balance the bran which is removed from the kernels. The larger size particles can be used to advantage as ,feed for grown or growing chickens, the smaller particles may be used to advantage as chick feed while the meal and bran may be employed for anyT of the useful or commercial purposes.

It is a prime object of the present invention to provide a machine, which, at one operation, will separate all of the different particles and accumulate them, in order that they may be disposed of in bulk.

With this object in view the machine includes a casing yhaving two alined screens therein. One of the said screens is of finer mesh wire than the other and the mixed material is deposited upon the screen of liner mesh. A shaft is journaled for rotation in the casing and is provided with reels, adapted to operate over the said screens. Means is provided for directing a v blast of air through the screen of coarser mesh, whereby the bran is removed from they material as it passes over the said coarser screen. Also, means are provided for directing a blast of air through the material which is discharged at the edge of the screen of coarser mesh, thus removing any particles of bran from the said discharge material which may remain in the same after subjected to the first mentioned blast of air. The bran which is removed from the material at the two points mentioned, is collected in a single chute or receptacle. When the mixed material first enters the casing and falls upon the screen of finer mesh, the meal is separated from the material, and gravitates through the said screen. As the material passes over the screen of coarser mesh, the relatively ne particles of corn or chick feed gravitate through ythe said screen. This material is accumulated in a suitable receptacle provided for its reception. The coarser particles of corn which leave the screen of coarser mesh, at the discharge edge or end thereof, is also accumulated in a suitable chute or receptacle.

Heretofore it has been the practice in preparing poultry feed to crack the corn and remove the meal and bran from the same. The corn thus cracked includes large and small particles, which may be used as feed for grown or growing chickens, but the appearance of this feed is detrimental in view of the presence of the smaller particles of corn. On the other hand, when the feed is prepared for baby chicks it is necessary t0 recrack the particles, inV order to reduce them to a standard uniform small size. This entails additional labor and time, and consequently, advances the market value of the cracked corn especially adapted to be used as baby chick feed.

Inasmuch as the present machine provides at one operation the feeds of both charac teristics, it will be seen that by the use of the machine great saving of time and labor is effected and at the same time advantage may be had of the best market prices for both kinds of feed in view of the fact that the large feed is uniformly large and the small feed uniformly small.
